The Tully-Fisher (luminosity-rotational velocity) relation is a
powerful tool to probe the evolution of galaxies, particularly
their
stellar populations and dark matter content. Here, we briefly
review
and propose methods to extend its use across all galaxy
morphological
types and to significant redshifts. First, and although they
are not
rotationally-supported, we show how good photometry and stellar
kinematics can be used to generate a Tully-Fisher relation for
early-type galaxies. This yields direct constraints on the
stellar
mass-to-light (M/L) ratios and dark matter, but is very
time-consuming. We simultaneously show that spiral galaxies can
not
simply passively evolve into lenticular (S0) galaxies, but must
also
compactify in the process. Second, we demonstrate that CO is,
unexpectedly, an excellent kinematic tracer in early-type
galaxies,
and analyse potential pitfalls. We verify that CO molecular gas
can
thus be used trivially for Tully-Fisher studies across all
galaxy
types, and recover more time-consuming results. Third, we
describe an
ongoing NANTEN2 project to establish a reliable z=0 CO
Tully-Fisher
benchmark, and discuss how this can be extended to intermediate
redshifts with ALMA. We also introduce the second generation
VLT
instrument KMOS, a near-infrared spectrograph with multiple
deployable
integral-field units. We discuss how KMOS guaranteed time will
be used
to probe the Tully-Fisher relation of disk galaxies at
intermediate
redshifts, using ionised gas. A bright, renewed future for
Tully-Fisher studies thus emerges, promising studies to
significant
redshifts and the elimination of the systematic errors usually
arising
when comparing galaxies of different morphological types.
